Keep in mind, the source code is for the 2.0, not the Artisan. They haven’t uploaded the source for the Artisan as of yet, but if I recall (can’t remember where the post was) they were going to begin updating the gcode reference again soon. We’ll see.
As far as activating the second diode in the 10W, I’ve had no problems with the 10W on my 2.0 and have used Lightburn exclusively. I wonder if they set it up to turn off one laser if under 50% or something, which wouldn’t make sense as that would create an uneven wear between the diodes.
EDIT: Generated the same file with 100% power and 1% power, no difference. Also, swapped Luban to the 1.6W aaaand… the line is still present. Digging a little further; it’s apparently for the 40W only. Swapping the machine settings to the 40W enables this option;
Which changes the line to M2000 L23 P0 at the beginning, then P1 again at the end. I’m more wondering what the M2003 and M2004 are. I’m going to do a few more tests real fast.
EDIT2: Did a quick test and it seems to not do anything, at least on a 2.0 with 10W. Quickly did up a test using grayscale (which would show the power reduction quite obviously) 0-100% power. One has P1 set, the other has P0 set, so one should be half the power of the other (one diode vs both) and…?
(sorry for running into a previous test under it, also I have the interval wide as not to overburn and ruin the test)
Exactly the same. So it seems it likely ONLY works with the 40W. My guess is the diodes in the 10W are in series together, meaning if one is on, the other is on. Whereas the 40W likely has 4 diodes in series on one board, and the other 4 on a separate board so it can turn half of them off. This will give you a tighter spot (similar to the 20W I assume) but again, it also puts more wear on the set of 4 that are always used, despite the setting.
